Application filed July 28, 1926, Serial No. 125,067, and in Germany July2 9, 1925. This invention relates to an'apparatus for instance 7, 8,,etc., so that each can be ascertaining colors, which is characterizedquickly and easily found when .desired/ by the fact, that upon each ofthe cards of 1 The fulcrum point for the several cards 50 celluloid,fan-like arranged around a comis formed in the known manner by a. pin12,

disposed both in radial direction and in In the fan, constructed asabove described, concentric rings, besides of which openings thegradations appertaining to one special differently shaded oil specimensof colors color "are found once by progressing along 55 are fixed, whichpermit by glancing through a concentric zone, secondly by progressing 10 them an immediate comparison with'the obin a radial direction andthirdly by pursuserved object. I ing the gradation of one special colorfrom The reading of the specimen of 'color is card to card; thegradations appear through given by the number .of the 'fan-segment theopenings when small rotations take 00 and secondly by the location ofthe color place. This apparatus permitsnot only a upon this fan-segment.close combination of numerous specimens in In the drawing the newapparatus is their relationship, but also the possibility of shown in afront view (Fig. 1) and in a quickly finding the desired color ofcornside view (Fig.2) of theclosed apparatus parison, because all 'thecolors, which are 05 and in a front view (Fig, 3) of the openedapproximately similar to the desired color fan. are located immediatelybesides each other In the represented form of execution the 'upon onefan-card and in a corresponding apparatus contains five, segmental cardsof ring of one of the neighboring cards. celluloid or of any otherconvenient mate- Besides these advantages, offered by the 70 rial; thesecards are designated by the numnew fan in comparison'with prior forms ofbers 1-5. Each of these cards contains a execution, as color steps forinstance, the

This shading off of the colors over approximately 200colors, when 7 -8 takes place not only in the circumferential fan-cardsare applied and each fan-card is so direction but in the radialdirection of the 24 by 39 cm., and when the specimen of rings a, b, aformed by the succeeding colors are 2,5 cm; high and not less than 1openings and specimens of colors.

If the specimenshave half the other hand the colors are shaded off from indicateddimensions and if they are doubly card to card. pasted, 400 colors canbe looked over. s5 The first card possesses a centrally located I Thenew model is first of all thought for 4 opening 7 which permitsinspection of all the color standards wllhelm Ostwald. the colors of thedifferent cards, whereas But they can also be applied for the compareachof the other cards shows an opening ing determination of any otherniaterials 8, 9, 10, 11, just beneath the opening 7 of (woven materials,minerals, metals, glass). or 90 the first card 1.

Having now particularly described and ascertained the nature of my saidinvention 5 and in what manner the same is to be performed, I declarethat what I claim is 1. In a device for. ascertaining colors, aplurality of cards of celluloid, means pivotally connecting the severalcards together,

10 each card having groups of openings arran ed in. rows concentric tothe axes of the car and spaced in'the radial direction of the saidcards, difierently colored specimens applied to the cards at the sidesof said openings. v

2. In a device as claimed in claim 1, characterized by the fact that thelocation of the specimen of color is given by the number of the fansegment and by the location of the color specimen thereon.

In testimony whereof I have signed my name to this specification.
